Vector exhaust tail pipe device, control system thereof and vehicle

Abstract

The invention discloses a vector exhaust tail pipe device, a control system of the vector exhaust tail pipe device and a vehicle. The vector exhaust tail pipe device comprises a connecting mechanism,height adjusting mechanisms, crank rocker mechanisms and a plurality of air guide plates. One end of the connecting mechanism is connected with the cold end of an exhaust tail pipe, and the air guideplates are arranged along the surface of the other end of the connecting mechanism in an array mode and rotationally connected to the surface of the connecting mechanism. The air guide plates are perpendicular to the cross section of the connecting mechanism, and a cavity is defined by the multiple air guide plates at the other end of the connecting mechanism to form an exhaust port. The height adjusting mechanisms are fixedly connected to the connecting mechanism, the height adjusting mechanisms are meshed with crank end gears of the crank rocker mechanisms, the rocker ends of the crank rocker mechanisms are fixedly connected with the air guide plates, and the crank rocker mechanisms are used for driving the air guide plates to rotate under the driving of the height adjusting mechanisms.The section of the exhaust tail pipe can be increased or decreased along with the rotation of the air guide plates, and it is achieved that the section of the exhaust tail pipe can be changed so as tobe matched with the working condition of an engine.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vector exhaust tailpipe device, a control system thereof and a vehicle. Background technique [0002] The exhaust tailpipe is a common structure of the cold end of the powertrain of a fuel vehicle. At present, most of the exhaust tailpipe structures commonly used in the market are fixed long round tailpipes, and the cross section of the tailpipe is fixed; secondly, every exhaust tailpipe currently on the market The shape of the exhaust tailpipes on the car is fixed, the geometric shape cannot be changed, and the shape is single; moreover, the throttle valve of the exhaust pipe currently uses a motor-controlled throttle valve, and the throttle valve can only reduce the cross-section of the exhaust pipe in one direction. Exhaust back pressure cannot be adjusted in multiple directions or the cross section of the tailpipe can be increased to reduce the exhaust back pressure. [0...
